Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: an aerator comprises an aerator body 7, wherein the aerator body 7 comprises three groups of aeration pipes 71 which are arranged in parallel in the front-back direction and two groups of connecting pipes 72 which are arranged in parallel in the left-right direction, two rows of aeration holes 76 are formed in the upper ends of the aeration pipes 71, two ends of the middle aeration pipe 71 are respectively communicated with the middle parts of the corresponding connecting pipes 72, and the left end of the aeration pipe 71 on the rear side is connected with an air inlet 8;

the rear end of the right connecting pipe 72 is connected to the right side of the rear aeration pipe 71 through a first elbow pipe 73, the front end of the right connecting pipe 72 is connected to the right side of the front aeration pipe 71 through a second elbow pipe 74, the front end of the left connecting pipe 72 is connected to the left side of the front aeration pipe 71 through a third elbow pipe 75, and the rear end of the left connecting pipe 72 is communicated with the air inlet 8.
